I was pumping out eggs in gen 2 for totodiles and charmanders that had crunch and earthquake. >.>
Jolteon also learned pin missile and double kick as early as Pokemon Yellow, if not in R/B as well.
Honestly, the game would be too easy if everything only ever used moves of their own types (although seeing that Fearow hit me with a ground-type move in B/W2 was pretty funny. Yay for Bug/Electric covering some weaknesses!)
